Abstract
The invention discloses a large-scale precision radial tire combined-type capsule die which comprises an upper die and a lower die, wherein the upper surface of the lower die is provided with a rubber injecting port device; a core is arranged on the inner side of the upper die and the lower die; an internal die cavity is arranged between the lower die and the core; the rubber injecting port device comprises a horizontal bottom ring which is connected with a peripheral baffle ring; the horizontal bottom ring is arranged in a peripheral concave table on the upper surface of the lower die; and the peripheral baffle ring is positioned on the outer side of the upper die. The invention has the advantage of reasonable structure, and the rubber injecting port device ensures that the rubber can smoothly enter the die cavity, thereby ensuring no rubber leakage; and the upper die, the lower die and the core are precisely positioned without adhesion and die bite and can be opened and closed freely. The clamping pressure reaches more than 5000 tons, the bearing pressure of the steaming chamber is 2.5 MPa, and the invention passes the hydraulic test.
Description
Technical field:
The present invention relates to a kind of tire combined-type capsule die.
Background technology:
Existing radial capsule die, owing to reasons such as structures, it is very not smooth that sizing material enters die cavity, leakiness glue, upper and lower mould and core accurate positioning are undesirable, easily adhesion under high temperature, high pressure conditions, gnaw mould, sting mould.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructurely, do not leak glue, folding large-scale precision radial tire combined-type capsule die freely.
Technical solution of the present invention is:
A kind of large-scale precision radial tire combined-type capsule die is characterized in that: comprise upper die and lower die, the counterdie upper surface is provided with the gum-injecting port device, and upper and lower mould inboard is provided with core, is die cavity in the mould between upper die and lower die and the core; The gum-injecting port device comprises the bottom level ring, and the bottom level ring is connected with the periphery baffle ring, and the bottom level ring is arranged in the periphery concave station of counterdie upper surface, and the periphery baffle ring is positioned at the patrix outside.
The degree of depth of counterdie upper surface concave station is identical with the bottom level ring thickness of gum-injecting port device.
Upper die and lower die, core main part adopt mild steel, and copper or ductile cast iron material are adopted in core and upper and lower mould turning joint position.
The exhaust line of die cavity is carried out muscle mould one in the mould, and upper and lower mould and core are controlled in 0.3 millimeter with the core degree, and upper and lower modular surface precision is controlled in 0.4 millimeter.
The present invention is rational in infrastructure, and the gum-injecting port device guarantees that sizing material enters die cavity smoothly, does not leak glue; Upper and lower mould and core accurate positioning, under high temperature, high pressure conditions adhesion, do not gnaw mould, do not sting mould, folding freely.Clamping pressure reaches more than 5000 tons, and it is 2.5Mpa that vaporium bears pressure, and the water pressure test by 2h.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of one embodiment of the invention.
The specific embodiment:
A kind of large-scale precision radial tire combined-type capsule die comprises patrix 1, counterdie 2, and the counterdie upper surface is provided with the gum-injecting port device, and upper and lower mould inboard is provided with core 3, is die cavity 4 in the mould between upper die and lower die and the core; The gum-injecting port device comprises bottom level ring 5, and the bottom level ring is connected with periphery baffle ring 6, and the bottom level ring is arranged in the periphery concave station of counterdie upper surface, and the periphery baffle ring is positioned at the patrix outside.The degree of depth of counterdie upper surface concave station is identical with the bottom level ring thickness of gum-injecting port device.Upper die and lower die, core main part adopt mild steel, and copper or ductile cast iron material are adopted in core and upper and lower mould turning joint position.
The exhaust line of die cavity is carried out muscle mould one in the mould, and upper and lower mould and core are controlled in 0.3 millimeter with the core degree, and upper and lower modular surface precision is controlled in 0.4 millimeter.
During work, place glue at the bottom level ring of gum-injecting port device, patrix is placed on the bottom level ring of glue filling device then, and glue enters interior die cavity under pressure.
" large-scale " of the present invention is meant that diameter is 1.8 meters and above capsule die series of products.
